6 months open to the Mobile Alliance

6 months open to the Mobile Alliance

Li tianjian 2003.02.13

Open global standards are the basis for data business development. Open Standards and interconnection allow businesses to be quickly accepted by users, and provide developers with platforms with economies of scale. I now receive about a dozen text messages every day, from jokes from friends, industry news, stock news, notifications of meetings in the company, and exchange information. I also need to send more than 10 text messages. My trust and dependency on text messages have made it a part of my life. The reason why I use text messages so rudely is that it is as reliable as the phone number, no matter what brand of the other phone is, what network is used, and which carrier is used, anyone else can contact me via text message without error. The success of the text message business has cheered the mobile communication industry, as the entire value chain from content providers, operators, equipment suppliers, and end users has tasted the sweetness of the mobile communication industry. There are many factors for text message success. One of the most important factors is the open standards and interconnected services. In the mobile communication industry's transition from voice to value-added services, open global standards are the basis for the development of data services. Open Standards and interconnection allow businesses to be quickly accepted by users, and provide developers with platforms with economies of scale. In June this year, more than 200 companies in the mobile communication industry set up the Open Mobile Alliance (OMA) in Vancouver, Canada, to jointly build a solid foundation for the mobile industry to take off. If OMA in Vancouver is just a newborn baby with infinite hopes in the industry, he is already a healthy teenager standing on the starting line at the second plenary meeting in Hawaii six months later. In just six months, Oma completed its organizational structure: the Board of Directors was elected, and Nokia's Jari alvinen was elected chairman of the board. At the same time, Oma has completed the integration of LIF, MMS-IOP, SyncML, Wireless Village and other standardization organizations, these organizations become Oma working groups. Now, mgif (mobile gaming interoperability Forum/mobile gaming interconnectivity Forum) and mwif (mobile wireless Internet forum/mobile wireless Internet forum) have announced their plans to integrate into Oma. At the COMDEX exhibition held in Las Vegas at the end of November, Oma finally broke out and released the first batch of eight technical specifications, beginning to produce substantial progress. Regulations released in Las Vegas include: 　　 Oma browser (browsing) 2.1 When users can browse the rich content on the Internet through limited memory, processing, bandwidth resources, and user interfaces of mobile terminals, they can enjoy a wider range of services and a more convenient interface, and more effective experience. By controlling the browsing experience, operators also create loyal user groups for their own brands. Oma browsing (browsing) 2.1 defines application-level protocols, semantics, syntax, and terminal software behavior for browsing functions of mobile and wireless handheld devices. 　　 Oma content download (delivery/content OTA download) Version 1.0 Simple mobile phone downloads, such as ringtones and icons, have become one of the important sources of revenue for the mobile communication industry. The commercial use of Java applications, Midi ringtones, and other technologies will bring content downloads to a new climax. The current HTTP (or WSP) technology has allowed content download. However, the server cannot know whether the client has been downloaded successfully, and thus cannot guarantee payment. The Oma content download technology solves this problem and ensures the development of mobile commerce. 　　 The specification consists of three parts: Download architecture 1.0 aims to download media content from the Internet in a simple and reliable manner and ensure payment. Due to the urgency of deploying the standardized solution, the functions originally managed by digital copyrights-preview and replication protection, are also included in the standards. As a billable technical platform, the general content OTA download (generic content download over the air) Version 1.0 encourages content providers to provide users with high-quality content. The Specification defines special requirements, such as content discovery, authentication, transfer negotiation, content transfer and delivery receipt. The download technology release definition (enabler release definition for download) Version 1.0 defines application-level protocols and behaviors. 　　 OMA (Digital Rights Management) 1.0 Digital copyrights protect the interests of all value chain members and provide them with brand new sales and distribution channels. Oma Digital Rights Management 1.0 is the world's first digital copyright standard and is applicable to various media formats and transmission formats. The regulations define three methods for copyright management: Content preview authorization, illegal forwarding (replication) control, and super release authorization. Content Providers control the publishing of digital media content by setting usage permissions for the content. The specification also defines the form of digital copyright encrypted media content and the associated metadata. Oma Digital Rights Management 2.0 covers protection of high-value content, such as high-quality music and games. 　　 Oma Domain Name Server 1.0 Although the network interface can recognize hosts using IP addresses, people are still used to using host names. In TCP/IP, the domain name system is a distributed database that can contact the domain name and host name. Domain Name Server (OMA) Version 1.0 defines the communication protocol between the client and the server, including the functions of the Domain Name System Client, while maintaining compatibility with IETF specifications. The regulations do not stipulate the behavior of the Domain Name Server, so the wireless client can look for the domain name in the original domain name system. This specification complies with both IPv4 and IPv6 address rules. 　　 Oma email notification (email push notification) Version 1.0 E-mail Notification (emn) can be sent to the emn terminal through the wap push architecture. The Oma email notification (email push notification) Version 1.0 defines the content format of the email. It is applied on the client of the emn terminal, that is, the emn operation and the client response are triggered. This specification is independent of protocols such as POP3 or IMAP4 email. However, the specification uses instances to identify possible email notifications and requirements. Because emn content is one of the XML applications, the specification also defines wbxml labels to ensure effective OTA transmission. 　　 OMA (instant messaging and Presence Services) 1.1 Real-time information and status reflect a new contact experience for users and create conditions for operators to open up new businesses. This service includes status representations, instant information, online group, and content sharing. The status includes the terminal status (ON/OFF the terminal, and on-line voice), user status (you can answer the phone, but cannot answer the phone, or in the conference), location, terminal capability (voice, text, GPRS, MMS) and personalized status (happy, angry) and hobbies (football, phishing, computer, dancing ). Because the status is often personalized, it is only open to user-specified groups. Instant Messaging: concepts familiar with mobile and fixed worlds, such as chat, two-way messaging, and two-way paging. Online cluster: operators and end users can create clusters. Users can invite their friends or family members to chat in the cluster. operators can create online chat opportunities for similar users. Content sharing creates shared buckets for users. Users can share images, music, and other multimedia content while chatting. 　　 Oma MMS (Multimedia Messaging/MMS) Version 1.1 The specifications specify the features executed by the proxy relay on the MMS client and the MMS server in the execution of the MMS business, as well as the overall architecture and protocol of the MMS business. 　　 Oma terminal File Management (User Agent/device profile) Version 1.1. Terminal file management allows operators to conveniently and effectively manage terminals and set information to ensure user experience. This information includes (but is not limited to) the hardware and software features of the terminal and the network information of the terminal. The terminal file stores the information used for content format. The terminal file is different from the user file. It stores information related to the application that the user selects. At the same time, Oma also published the following specifications for public comment: Wireless Identity Module 1.1 Wireless Session Protocol Version 1.0 The Institute of transmission of the Ministry of Information Industry of China also participated in OMA following China Mobile. Now, Oma includes more than 300 member organizations in all aspects of the global region and industrial chain. As a member of the board of directors and one of the founding companies, Nokia and oma are open-minded. With its years of experience in the industry, Nokia has been actively contributing to the development of OMA. Nokia participates in the work of multiple Oma Working Groups and undertakes the development of technology and interconnection Protocols within the framework of OMA. The success of Short Messages indicates the infinite potential of wireless data services, a new world, and the newly-used MMS services show the importance of opening standards in this new world. On the one hand, the mobile communication industry faces more complex terminals, more complex platforms, more complex content, and more complex services. On the other hand, users require the same experience, the same reliability, and more convenient services as the services they are familiar. The open standards, frameworks, and sound interconnection of the entire industry have become more urgent. Oma has proved that it can effectively develop open global standards while accommodating the entire industry value chain, laying a solid foundation for the soaring mobile data business!
